Abstract
Polystyrene latex particles with the diameter of ≈1 μm in water were laser trapped in spatial images of a laser beam. For a mixture of latex particles with different diameters, delicate tuning of the images resulted in size selection of the particles. Directional flow of the particles in water was also achieved by laser irradiation.Keywords
